Be it lmowi that i, HARRY A, STEPHENS;

e citizen of the 'il'uited States, residing at Missoule, in tire county of Missouie and idiote oi llioritaim,l1eve invented oerteionew :uid useiioi improvements in Closures for THessels, of which the following is o speciiicetioi A present invention pertains to improvements in Closures for `vessels, and hais reference more particularly to means for hermetieeliy sealing e. jar, and also to the peculiar formation of the cover orclosure" which tends, as it is positioned, to force out the sir from the materiel contained Within the jor, md likewise such oir es may be filiere the material, prior to'. the seoliiig oi' tile closure. v

The construction also provides e reservoir or the sealing .materiel and, consequently, provides eri easy means oi introducing the @me the iock between the closure end body of the receptacle.

The invention is iliustrated in the eik tiered drawings, wherein:

The outer diameter of the closure is less than the internal diameter of the upper inner Well oi' the jor; or in other Words, the.

the upper edge of tile jar, and will thus afford e. means whereby e pry may rloe irx;`

serted beneath the said edge when it desired to remove tile-cover. The closure is provided in its upper fece with o.A chamber or receptacle 9, adopted to receive end liold e supply 'of sealing materiel, sueh paraffin, wax or any other suite'ble-mo'terieii which when coid wiiisetoud securely hold the cover in position.

@peiling outwardly from the chamber 9 is e seriesof grooves or channels i0, which are preferably narrower et the bottom than et tlie to seid cimimels extending through the perip ery of the cover mid opening; into the space formed between theimier Weli oi' tile jar and the outer vertical ieee or Wall of thev cover.

Within the jor :ood my eirirulibles will 'travel upwardly and outwerdiy along tlie inciined face 5, passing thence ibeiieetii the cover and out between the edge ofthe cover and the mier Well of the ier. When the.

.cover comes ,to rest upon the seat E2 tlie seal ing material may loe poured into the cimmloer or' reservoir 9 and Wili flow outwardly therefrom through the radially disposed grooveshor oir-soucis 10 into the space be tween tne cover and the Weli oi the jar,

The sealing material left'within the reservoir S) will adh re to the cover and also till the' channels 10. hen the coveris-again used,

Vafter having been removed, the heat trans' mitted thereto from the material contained.

Withinthe jar will tend to melt the sealing v2aunedium'-contained in the chamber or reservoii' 9 and thereby again seal the jar, without further attention on the part 'of the operator or attendant. WVhen the material is packed cold'it is, of course, necessary to 30 apply heat to the sealing medium to cause Having thus'vfully described my invention, what I claim is:
